General Information
A Zeolite Rotor with RCO is an industrial air pollution control system that uses a Zeolite rotor concentrator to capture and concentrate Volatile Organic Compounds (VOCs) from large air volumes, which are then fed into a Regenerative Catalytic Oxidizer (RCO) to be destroyed.
This combined system is highly effective for treating large, low-concentration air flows, as the rotor significantly reduces the air volume and increases the VOC concentration, making the oxidation process in the RCO more fuel-efficient.
